[0002] With the continuous improvement of people's living standards, air conditioners have become a necessity in people's daily lives. Air conditioners not only provide indoor cooling and heating, but also improve indoor air quality. Installing an air conditioner indoors can improve the comfort of the indoor environment. Existing technologies use pyroelectric temperature sensors or thermopile array temperature sensors to detect the presence of people indoors, enabling shutdown. They also detect the position of the person relative to the air conditioner, allowing the air to flow directly to or away from them. However, as people's demands for comfort grow, air conditioners must also be increasingly precise in controlling the air supply to specific individuals. For example, people with a cold and fever are not suitable for air conditioning.

[0031] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for controlling an air conditioner according to an embodiment of the present invention. Figure 2 As shown, the air conditioner in this embodiment is a cabinet air conditioner, which is equipped with a display module, a voice playback module and an infrared temperature sensing module, wherein the display module can be a display panel, such as an LED display; the voice playback module is a voice speaker, which interacts with the user by voice; the infrared temperature sensing module includes multiple CMOS infrared temperature sensors, and the multiple CMOS infrared temperature sensors form an infrared temperature sensor array, which is installed at a height of 1.5m to 1.8m on the cabinet air conditioner, horizontally or slightly tilted downward, so as to achieve the detection of the entire scene and the temperature of the human forehead as much as possible. For example, in this embodiment, the temperature acquisition array is 60×80 (i.e., 4800 pixel temperature points), as shown in FIG. Figure 3 As shown, the horizontal viewing angle A≥90° and the vertical viewing angle B≥60° form a certain effective detection area; in other embodiments, the temperature acquisition array can also be a higher number of arrays. It is understandable that the more the number of temperature acquisition arrays, the more accurate the recognition of human body temperature, distance test and human position test will be. The CMOS infrared temperature sensor has the advantages of low cost and high precision. The control method of the air conditioner is described in detail below. Figure 1 As shown, the method includes the following steps S110-S140.

[0032] S110: If an intelligent comfortable air supply instruction is received, whether a body surface temperature collection condition is met is detected based on the collected multiple first infrared temperature values.

[0033] In an embodiment of the present invention, a user activates intelligent comfort air supply via a display panel button, remote control, or app, causing the air conditioner to enter intelligent comfort air supply mode. When the air conditioner enters intelligent comfort air supply mode, it receives an intelligent comfort air supply command. Upon receiving the intelligent comfort air supply command, the air conditioner collects multiple first infrared temperature values ​​using multiple CMOS infrared temperature sensors and detects whether the body surface temperature collection condition is met based on the multiple first infrared temperature values.

[0034] In some embodiments, such as the present embodiment, Figure 4 As shown, the step S110 may include steps S111-S114.

[0035] S111. For each of a first preset number of acquisition cycles, collect a plurality of first infrared temperature values, and calculate an average value of the plurality of first infrared temperature values ​​to obtain a plurality of first average infrared temperature values ​​corresponding to the acquisition cycle;

[0036] S112, calculating the difference between the first average infrared temperature value corresponding to the latter acquisition cycle and the first average infrared temperature value corresponding to the former acquisition cycle in two adjacent acquisition cycles to obtain an average infrared temperature difference;

[0037] S113: If the average infrared temperature difference is greater than the preset infrared temperature difference, continue collecting first infrared temperature values ​​for a second preset number of collection cycles, and calculate the average of the first infrared temperature values ​​in each collection cycle to obtain a plurality of first average infrared temperature values ​​corresponding to the collection cycles;

[0038] S114: If the plurality of first average infrared temperature values ​​are all greater than a preset infrared temperature threshold, it is determined that the body surface temperature collection condition is met.

[0039] In an embodiment of the present invention, the cabinet air conditioner further includes a main control unit, which collects infrared temperature values ​​of 60×80 array points of the CMOS infrared temperature sensor in a certain collection period, wherein the collection period is T. In this embodiment, the value of T is any value from 0.3s to 1s; the main control unit collects multiple first infrared temperature values ​​for each collection period in a first preset number of collection periods, and calculates the average value of the multiple first infrared temperature values ​​to obtain multiple first average infrared temperature values ​​corresponding to the collection period, wherein the first preset number is 4; for ease of understanding, it is assumed that the first average infrared temperature values ​​corresponding to the first collection period, the second collection period, the third collection period, and the fourth collection period are T respectively. n 、T n+1 、T n+2 and T n+3 , a is the preset infrared temperature difference; calculate T n+3 -T n+2 、T n+2 -T n+1 and T n+1 -T n , if T n+3 -T n+2 >a、T n+2 -T n+1 >a and T n+1 -T n>a, indicating that the overall infrared detection temperature field increases and a user is approaching the air conditioner; the main control unit collects multiple first infrared temperature values ​​for each collection period in the second preset number of collection periods, and calculates the average value of the multiple first infrared temperature values ​​to obtain multiple first average infrared temperature values ​​corresponding to the collection period, wherein the second preset number is 3; assuming that the first average infrared temperature values ​​corresponding to the fifth collection period, the sixth collection period, and the seventh collection period are T n+4 、T n+5 as well as Tn+6 , b is the preset infrared temperature threshold; if T n+3 >b、T n+4 >b、T n+5 >b and T n+6 >b, indicating that the user is sufficiently close to the air conditioner and is stably within the effective distance detection area, thus satisfying the body surface temperature acquisition conditions. Understandably, the closer the user gets to the air conditioner's CMOS infrared temperature sensor, the higher the overall temperature radiated by the human body, i.e., the first average infrared temperature value, will also increase.

[0040] S120: If the body surface temperature collection condition is met, calculate the human body surface temperature based on the collected multiple second infrared temperature values ​​and the acquired ambient temperature.

[0041] In an embodiment of the present invention, if the surface temperature collection conditions are met, the internal fan is controlled to shut off, thereby stopping cooling or heating. This prevents the user from being exposed to cold or hot air at close range, which could cause discomfort, and also prevents the air from blowing directly onto the user, which could distort the temperature measurement. After shutting off the internal fan, the system also includes prompting the user to stand in a suitable position via voice announcement, for example, such as, "The air conditioner is about to collect your surface temperature. Please stand within 1 meter of the air conditioner for 3 seconds." The display on the air conditioner's display panel is cleared, and the display is set to a preset value, which is then flashed. For example, if a conventional air conditioner's display panel displays a target set temperature or indoor ambient temperature, the display is cleared and replaced with a temperature value of 00.0, and temperature detection is triggered until the detection is successful. During the temperature detection period, the temperature value of 00.0 flashes to remind the user that surface temperature collection is in progress. The CMOS infrared temperature sensor collects multiple second infrared temperature values, the temperature sensor collects ambient temperature, and the human surface temperature is calculated based on the multiple second infrared temperature values ​​and the ambient temperature.

[0042] In some embodiments, such as the present embodiment, Figure 5 As shown, the step S120 may include steps S121-S123.

[0043] S121, collecting multiple second infrared temperature values, wherein the multiple second infrared temperature values ​​are temperature values ​​corresponding to the forehead area of ​​the human body;

[0044] S122: If the plurality of second infrared temperature values ​​are all within the preset temperature range, calculating an average value of the plurality of second infrared temperature values ​​as the initial human body surface temperature;

[0045] S123: Acquire the ambient temperature, and compensate the initial human body surface temperature according to the ambient temperature to obtain the human body surface temperature.

[0046] In an embodiment of the present invention, the highest k infrared temperature values ​​in the infrared temperature sensor array are collected (under normal circumstances, when a user is close to the air conditioner, the highest temperature value detected by the infrared temperature sensor is generally the temperature of the user's forehead. The k infrared temperature values ​​are the number of temperature points occupied by the exposed area of ​​the user's forehead when the user is close to the air conditioner). If the k infrared temperature values ​​are all within the preset temperature range, where the preset temperature range is between 34°C and 37°C, it means that the k infrared temperature values ​​are valid. If they are not between 34°C and 37°C, it means that the k infrared temperature values ​​are invalid and need to be collected again. It can be understood that after collecting k valid infrared temperature values, the average temperature value of the k infrared temperature values ​​is calculated as the initial human body surface temperature T k Obtain the ambient temperature, and compensate the initial human body surface temperature according to the ambient temperature to obtain the human body surface temperature. It should be noted that if T k If both are lower than the preset temperature c, it means that the user has exited the effective distance detection area of ​​the air conditioner.

[0047] In some embodiments, such as the present embodiment, Figure 6 As shown, the step S123 may include steps S1231-S1233.

[0048] S1231, calculating the difference between the initial human body surface temperature and the ambient temperature to obtain a temperature difference value;

[0049] S1232, calculating the product of the temperature difference and the compensation coefficient to obtain a temperature compensation value;

[0050] S1233. Calculate the sum of the temperature compensation value and the initial human body surface temperature to obtain the human body surface temperature.

[0051] In the embodiment of the present invention, it is assumed that the ambient temperature is Tenvironment, β is the compensation coefficient value, ΔT is the temperature compensation value, and the human body surface temperature is T 显示 , first calculate T k- T 环境 , then calculate △T=β×(T k -T 环境 ); finally calculate T显示 =△T+T k , calculate T 显示 Afterwards, the display content is set to the human body surface temperature T 显示 , and maintains the preset display time, where the preset display time is 3s to 10s; the air conditioner simultaneously announces the detected human body surface temperature through voice broadcast. If the human body surface temperature is greater than a preset human body surface temperature threshold, the user is prompted that the body temperature is abnormal, where the preset human body surface temperature threshold is 37.3°C. It should be noted that in this embodiment, if the display time reaches the preset display time, the human body surface temperature detection working state is exited, the display panel resumes displaying the original display content of the air conditioner, and the internal fan is controlled to turn on, resuming the cooling or heating working state of the air conditioner.

[0052] S130: Determine the human body's temperature sensation based on the human body surface temperature and the ambient temperature, and calculate the relative angle of the human body with respect to the air conditioner based on the collected multiple third infrared temperature values.

[0053] In an embodiment of the present invention, a human body temperature sensation is determined based on the human body surface temperature and the ambient temperature. Specifically, as shown in Table 1, the human body temperature sensation includes cool, normal, and warm. The ambient temperature includes three temperature intervals: above 28°C, 26°C to 28°C, and below 26°C. The human body temperature sensation determined by the human body surface temperature T varies depending on the ambient temperature interval. For example, if the ambient temperature is 29°C and the human body surface temperature is 35.9°C, the human body temperature sensation is cool; if the ambient temperature is 27°C and the human body surface temperature is 35.9°C, the human body temperature sensation is normal; and if the ambient temperature is 27°C and the human body surface temperature is 37.1°C, the human body temperature sensation is warm. It should be noted that in this embodiment, the actual determination of the human body temperature sensation is not limited to the human body surface temperature range and the ambient temperature interval, and can be determined according to actual conditions.

[0054] Table 1

[0055]

[0056] Furthermore, after determining the human body temperature coldness, the relative angle of the human body relative to the air conditioner is calculated based on the collected multiple third infrared temperature values, wherein the relative angle is the horizontal angle of the human body relative to the air conditioner, specifically, Figure 7 As shown, the step S130 may include steps S131-S134.

[0057] S131, collecting multiple third infrared temperature values, and calculating an average value of the multiple third infrared temperature values ​​to obtain a second average infrared temperature value;

[0058] S132, calculating the sum of the second average infrared temperature value and a preset background value to obtain a target average infrared temperature value;

[0059] S133. For each of the third infrared temperature values, calculate the difference between the third infrared temperature value and the target average infrared temperature value to generate an initial array temperature table;

[0060] S134: Replace the values ​​in the initial array temperature table that are less than the preset temperature value with the preset temperature value to generate a target array temperature table, and determine the relative angle of the human body with respect to the air conditioner according to the target array temperature table.

[0061] In the embodiment of the present invention, the main control unit collects the third infrared temperature value of the infrared temperature sensor array point once in a certain collection period (0.3s to 1s), and calculates the average value of the plurality of third infrared temperature values ​​to obtain a second average infrared temperature value, which is recorded as T m For ease of understanding, the calculation method of the relative angle between the human body and the air conditioner is explained by taking a 10×10 infrared sensor array as an example. The third infrared temperature value collected by the 10×10 infrared sensor array is shown in Table 2. The bold area in Table 2 is the user position, so the temperature value is higher. Assuming a is the preset background value, the target average infrared temperature value is calculated as T m +a, for each of the third infrared temperature values ​​in Table 2, calculate the difference between the third infrared temperature value and the target average infrared temperature value to generate an initial array temperature table, the initial array temperature table is shown in Table 3, replace the values ​​in Table 3 that are less than the preset temperature value with the preset temperature value to generate a target array temperature table to eliminate the background array temperature value, the target array temperature table is shown in Table 4, wherein the preset temperature value is 0, and the relative angle of the human body with respect to the air conditioner is determined based on the target array temperature table. It should be noted that, in this embodiment, the preset background value is the value obtained when a large number of tests are performed on the human body surface temperature and background temperature values, and the background temperature value is the temperature value of the area other than the human body. It should also be noted that the reason for eliminating the background array temperature value is to facilitate the positioning of the human body.

[0062] Furthermore, in Table 4, the non-zero part is the position of the thermal imaging array of the human body. The relative angle of the human body to the air conditioner can be calculated based on the position of the thermal imaging array of the human body. Assuming that the horizontal detection angle of the infrared sensor is 100°, the middle position is defaulted to 0°, and the horizontal position of the mapped person is -10° to 10°, that is, the relative angle of the human body to the air conditioner is a horizontal angle of -10° to 10°. In order to better understand the calculation process of the relative angle of the human body to the air conditioner, an 18×12 infrared sensor array is used as an example. At this time, there are 18 acquisition points in the horizontal direction and 12 acquisition points in the vertical direction. The horizontal viewing angle is 90° and the vertical viewing angle is 60°. Figure 8As shown, a horizontal sensor array point is 5°, and a vertical sensor array point is also 5°. Figure 8 The relative angle of the human body to the air conditioner is 10° to 20° from the horizontal.

[0069] S140: Adjust the air supply parameters of the air conditioner according to the human body temperature and the relative angle.

[0070] In an embodiment of the present invention, after calculating the relative angle of a human body relative to an air conditioner, the air supply parameters of the air conditioner are adjusted based on the human body's temperature sensation and the relative angle, where the air supply parameters include the air supply angle and the air supply temperature. Specifically, if the human body's temperature sensation is normal or cool, the air supply angle is adjusted based on the relative angle; if the human body's temperature sensation is warm, the air supply angle remains unchanged. A target temperature corresponding to the human body's temperature sensation is obtained, and the air supply temperature is adjusted to the target temperature. More specifically, as shown in Table 5, human body temperature sensations include normal, cool, and warm, and target temperatures include cooling target temperatures and heating target temperatures. If the human body's temperature sensation is normal or cool, the air supply angle is adjusted based on the relative angle, with air supplied at an angle away from the user. If the human body's temperature sensation is warm, allowing the user to enjoy the air, the air supply angle remains unchanged. It should be noted that in this embodiment, setting different target temperatures based on different human body temperature sensations and the same cooling and heating modes can improve user comfort.

[0073]

[0074] It should be noted that in this embodiment, the human body surface temperature can be quickly measured by the infrared temperature sensor array, and the relative angle is calculated based on the human body surface temperature and the ambient temperature to provide reasonable air supply, thereby solving the problem that certain people are not suitable for blowing air and improving the comfort of certain people.
